</p> <p> 四、螺紋連接： </p> <p> 這是一種簡便的連接方法，常用于小閥門。又分兩種情況： </p> <p> 1、直接密封：內(nèi)外螺紋直接起密封作用。為了確保連接處不漏，往往用鉛油、線麻和聚四氟乙烯生料帶填充；其中聚四氟乙烯生料帶，使用日見廣；這種材料耐腐蝕性能很好，密封效果較好，使用和保存方便，拆卸時，可以完整地將其取下，因為它是一層無粘性的薄膜，比鉛油、線麻優(yōu)越得多。 </p> <p> 2、間接密封：螺紋旋緊的力量，傳遞給兩平面間的墊圈，讓墊圈起密封作用。山東專業(yè)閥門推薦</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="安徽專業(yè)閥門,閥門" src="http://tyunfile.71360.com/UpLoadFile/sdkgfm/2019/11/637087462844423094/6370874628444230949213331.jpg"></div><p> 密封性能要求 </p> <p> 閥門的密封性能是指閥門各密封部位阻止介質(zhì)泄漏的能力，它是閥門**重要的技術(shù)性能指標(biāo)。閥門的密封部位有三處：啟閉件與閥座兩密封面間的接觸處；填料與閥桿和填料函的配合處；閥體與閥蓋的連接處。其中前一處的泄漏叫做內(nèi)漏，也就是通常所說的關(guān)不嚴(yán)，它將影響閥門截斷介質(zhì)的能力。對于截斷閥類來說，內(nèi)漏是不允許的。后兩處的泄漏叫做外漏，即介質(zhì)從閥內(nèi)泄漏到閥外。外漏會造成物料損失，污染環(huán)境，嚴(yán)重時還會造成惡事件。對于易燃易爆、或有放射的介質(zhì)，外漏更是不能允許的，因而閥門必須具有可靠的密封性能。 </p><p> 按驅(qū)動方式分類分為自動閥類、動力驅(qū)動閥類和手動閥類： </p> <p> (1) 自動閥是指不需要外力驅(qū)動，而是依靠介質(zhì)自身的能量來使閥門動作的閥門。如安全閥、減壓閥、疏水閥、止回閥、自動調(diào)節(jié)閥等。 </p> <p> (2) 動力驅(qū)動閥：動力驅(qū)動閥可以利用各種動力源進(jìn)行驅(qū)動。分為電動閥、氣動閥、液動閥等。電動閥：借助電力驅(qū)動的閥門。氣動閥：借助壓縮空氣驅(qū)動的閥門。液動閥：借助油等液體壓力驅(qū)動的閥門。 </p> <p> 此外還有以上幾種驅(qū)動方式的組合，如氣-電動閥等。 </p> <p> (3) 手動閥：手動閥借助手輪、手柄、杠桿、鏈輪，由人力來操縱閥門動作。當(dāng)閥門啟閉力矩較大時，可在手輪和閥桿之間設(shè)置齒輪或蝸輪減速器。必要時，也可以利用萬向接頭及傳動軸進(jìn)行遠(yuǎn)距離操作。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

閥門是用來開閉管路、控制流向、調(diào)節(jié)和控制輸送介質(zhì)的參數(shù)（溫度、壓力和流量）的管路附件。根據(jù)其功能，可分為關(guān)斷閥、止回閥、調(diào)節(jié)閥等。閥門是流體輸送系統(tǒng)中的控制部件，具有截止、調(diào)節(jié)、導(dǎo)流、防止逆流、穩(wěn)壓、分流或溢流泄壓等功能。用于流體控制系統(tǒng)的閥門，從**簡單的截止閥到極為復(fù)雜的自控系統(tǒng)中所用的各種閥門，其品種和規(guī)格相當(dāng)繁多。閥門可用于控制空氣、水、蒸汽、各種腐蝕性介質(zhì)、泥漿、油品、液態(tài)金屬和放射性介質(zhì)等各種類型流體的流動。閥門根據(jù)材質(zhì)還分為鑄鐵閥門，鑄鋼閥門，不銹鋼閥門（201、304、316等），鉻鉬鋼閥門，鉻鉬釩鋼閥門，雙相鋼閥門，塑料閥門，非標(biāo)訂制閥門等。安徽專業(yè)閥門</p><p
